DId you read mod description? Answer is there. If still not working you need to upload savegame since that issue is not reproducible in normal conditions (link to guide is also in the description).

Try to reinstall TM:PE with the new version again as posted in the description. Also cleaned all mods according to the compatibility report mod without success.
I have uploaded my savegame:

The same thing happens to me and I already did the steps they say and it still fails

I think you didn't read the description carefully so I'll copy it for you:
Vehicles despawning after altering roads or rails? Use Broken Nodes Detector to find and fix some common game bugs!

Subscribe that mod, enabled and click Ctrl+0(zero, can be changed in the options) to open its menu after loading the savegame and run "Find broken nodes"(first option). It will find 4 broken bedestrian nodes (yes I've spent 20min subscribing assets and loading your savegame just to confirm what I already said).
Use Move it and either delete or move broken nodes closer to the road.
Sometimes when pedestrian path is too far from the road but still shows the connection (concrete path) it's not really connected and that will break on next savegame load. It's known issue but really rare, since you need to be quite precise with path placement to trigger the bug, hence why known solution is still mentioned in the mod description - despawn of vehicles after upgrading or building roads is always caused by that problem and likelyhood of triggering it greatly increases with the amout of pedestrian and bike paths created in the city.

Many thanks for the great support! Everything works fine now.
Have tried Broken Nodes Detector already a few days ago but searched for broken nodes directly on the path of the tram and around the updated road segment. I didn't get the link that it was caused by the pedestrian path miles away from the updated segment :(

HOLY $H!T, I've been having this exact same issue for a week now, and could not find an answer or anyone else having posted with the same issue. Disabling TMPE was my only solution, which makes the game much less playable so not a great solution. I also couldn't reproduce the issue myself in a new game with the same mods enabled

I cannot thank you enough for this solution!!!

I had already run broken nodes detector and yes it found one broken pedestrian path in some random spot on my map nowhere near any "problem" segments I had encountered so I also had no reason to suspect that as the issue!

May I make a kind suggestion to slightly clarify the wording of the description to indicate that the broken nodes found might seem to be entirely unrelated to the issue, but are indeed still the cause of the problem? I had completely ignored the two broken pedestrian nodes since even after carefully reading all the information on TMPE, I still couldn't imagine those two path nodes as being the reason why any new road on the map would stop working. The wording could say something more like "use broken nodes detector to find and fix ALL issues found, even if they seem unrelated"

Anyway, thank you Krzychu1245 and other devs for this amazing mod!!! (And thank you @fired for posting this issue so I could finally get resolution of my same problem!)

I've been playing around this week with TM:PE 11.7.1.2 STABLE (Traffic Manager: President Edition) but yesterday it started to bug out slowing down vehicles and traffic a lot for no apparent reason and all highway traffic flow crashing it to a specific point for no reason, it also applied some preference signals that I had obviously not applied so I had to uninstall it.

Is it fixed yet all those bugs or random crashes? It almost puts my whole game and progress in danger.

Run the broken nodes detector mod and fix ALL broken nodes it finds, whether they seem relevant or not (like a pedestrian path or train track). Doing that finally fixed the issue immediately for me

What bugs? What random crashes? What danger?
How can I reproduce problem if you don't provide enough details especially if you think that problem is random?
Pathfinding for vehicles can balance itself but if you constantly changing parameters don't expect it will work perfectly at any point of time. E.g. when you change lane arrow at some intersection it may greatly affect its throughtput especially on highways. Vehicles will notice the change but only when they reach the road segment that has been changed (otherwise it would require at worst scanning all path units for all vehicles which is ~250k units * 16k vehicles = 4 B updates for each road segment changed (~32k is the segment limit) but only if you don't use mods increasing limits like More Path Units or More Vehicles, they double the limit).

The best what you can do is share the savegame.
