after spamming 2-27 smoke granades in a row i could reproduce it still but definitely seems to be improved.
amount of granades to be spammed before bug occures:
first try: 8 Granades
seccond try: 2 Granades
third try: 27 Granades

i have this problem now more frequent even when the system is not under stress nor enfusion workbench open.

Seems to me this happens only when the system is already under stress.
Normally i get this problem just once a day but when im having the Enfusion Workbench also open it appears to me every second time. in this case reducing the resolution to reduce stress on the system doesn't even work well.

i guess you could easily use the Steam Controller mapper.
it maps to the xbox controls and then you could should be able to use the controls just like everyone else
